(I kept a copy of original wordle, and it seems to have 2,315 words that are possible answers.)
Not my experience at all.
Ask me how I know what an EPEE is

Really no harder than memorizing all the 2 and 3 letter words in Scrabble and many players will pick most up in a few months.
But I disagree that that makes it for snobs. Snobbery is more about an attitude of looking down on others or their tastes, whereas knowing Latin or being a fan of opera is really just about exposure.
Sure, there exist some (too many) opera fans who would say something like "it's real art compared to pop or hip hop being low class trash", but that's not a defining part of liking opera and plenty of people who like opera aren't snobs. Ironically it's a different form of snobbery (sometimes called reverse snobbery though personally I hate that term), to dismiss anyone who learned Latin or who likes opera as being a snob!
